npm install -g ionic cordova

ionic start image-storage blank --type=angular

cd image-storage

ionic cordova plugin add cordova-plugin-camera
npm install @ionic-native/camera

import { Camera } from '@ionic-native/camera/ngx';

...

@NgModule({
  ...

  providers: [
    ...
    Camera
    ...
  ]
  ...
})
export class AppModule { }

import { Camera, CameraOptions } from '@ionic-native/camera/ngx';

...

constructor(private camera: Camera) { }

...

takePicture() {
  const options: CameraOptions = {
    quality: 100,
    destinationType: this.camera.DestinationType.DATA_URL,
    encodingType: this.camera.EncodingType.JPEG,
    mediaType: this.camera.MediaType.PICTURE
  };

  this.camera.getPicture(options).then((imageData) => {
    // 将图像数据存储到数据库中
    // 这里可以使用适合你的数据库技术和方法来存储图像数据
  }, (err) => {
    console.log(err);
  });
}

<ion-button (click)="takePicture()">拍照</ion-button>
